| The control unit for the injection and ignition system is equipped with a fault memory. |
| If malfunctions occur in the monitored sensors or components, they are stored in the fault memory with indication of the fault type. |
| Stored information regarding the faults can be interrogated according to the instruction → Chapter. |
| After the fault(s) has(have) been removed the fault memory must be erased → Chapter. |
| A test drive of min. 10 minutes must be performed in order to interrogate the information regarding the fault according to the lambda control. |
| Faults due to a temporary line interruption or loose contact are also stored. These so-called temporary (sporadic) faults are shown as “SP” and if they do no longer occur during 40° vehicle starts, they are erased automatically in the fault memory. |
